JOHN F. MAKOWSKI, F STOCKTON, CALIFORNIA, ASSIGNOR, BY MESNE ASSIGNMENTS, TO FIRE PROOF WALL COMPANY, OF RENO, NEVADA, A CORPORATION.

METHOD OF CONSTRUCTING PLASTER-TILE WALLS.

No Drawing.

This application is a continuation in part and amplification of my application for patent, filed February 11th, 1926, Serial No. 88,574.

This invention relates to the building art and particularly to the construction of corridor and partition walls in class A buildings which are built upon a skeleton frame and of fire proof material. These must be fire proof and in the interest of economy of space must be very thin, corridor walls usually four inches and partition walls two inches. The now common ways of constructing this class of wall are by first erectr ing small channel iron studs and securing metal lath thereto and plastering over the same, or by constructing the wall of tile or blocks consisting mainly of gypsum, cement or like setting material. My invention relates to improvements over the latter method.

As now carried out the blocks or tile are made in their completely finished state at a plant distant from the building and are then carted to the building. The first cost is heavy, the cost of cartage considerable, and breakage quite common. Furthermore blocks thus made and handled require skilled labor to place and set them in the wall. All these things make the cost of the finished wall very high. It is the aim of my inven tion to do away with the conditions which create the excessive cost and at the same time produce a better appearing wall.

In carrying out my improved method I have the tile forming machine directly at the building. This may be of any desired type, preferably of the die press type. My improved tile is made preferably of a setting material such as calcined gypsum, cement or the like, a filler material such as sawdust or the like and clay. I mix the same in about the proportions of forty per cent of the setting material and forty per cent filler material and twenty per cent clay, all by volume. I intimately mix these with water preferably to the consistency of wet pottery clay, or so that the same will not be depressed .by handling or when a number of Application filed September 23, 1926. Serial No. 137,392.

tile made therefrom are placed one upon the other. As the material is being mixed I add a retarder thereto such as liquid glue or the like to retard the setting thereof from one to four hours.

lVhen the material is thus mixed I force it through the die press to form the tile and as fast as these are formed they may be placed in the Wall and there allowed to set, harden and dry. By setting up a temporary back to the wall the tile may be set to form a true Wall in very rapid fashion and with unskilled labor. Then after the tile has set hardened and dried, the temporary backing may be removed.

As'the green undried and unset tile are disposed one upon the other they will adhere one to the other without being mortared together. Or if they have dried out somewhat then they may just be brushed either with water of a weak solution of the same material of which the tile is made, thus assuring that they will adhere together in the wall. The tile are laid in successive rows around the wall so that as the height of the wall increases the tile in the lower rows have set so that they will not collapse under the Weight of the Wall above.

If a little care is used in setting up the wall it can be used in some instances Without the necessity of applying a finishing coat of plaster thereon.

It will be readily apparent that a wall constructed according to my new method can be erected at a very much lower cost than by the method described in the preamble to this specification.

From the foregoing description it will be readily seen that I have produced such a method as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred application of the method, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention what I claim as new and useful and desire to the tile in a moist and unset state building secure by Letters Patent is: them in a course in the Wall in that state, 10 1.
